ABSTRACT:
An ink ribbon feeding mechanism includes a rotatably supported capstan roller which is fixed in position and a rotatably supported pinch roller which is movable with respect to the capstan roller and normally biased toward the capstan roller to be pressed thereagainst with ink ribbon to be fed as being sandwiched therebetween. In the present invention, there is provided a structure which allows to keep the pinch roller separated away from the capstan roller when desired. In the preferred embodiment, it is so structured that the pinch roller is brought into contact with the capstan roller under pressure when a top cover is pivoted closed and brought out of contact with the capstan roller when the top cover is pivoted open, automatically.
